"Protestors are taking to the streets and community hubs nationwide on June 14 in what organizers expect will be the largest single-day anti-President Trump rally since the start of the administration.
Why it matters: The widespread movement will run counter to Trump's multimillion dollar military parade in D.C.
"No Kings is a nationwide day of defiance," organizers wrote. "From city blocks to small towns, from courthouse steps to community parks, we're taking action to reject authoritarianism."
More than 100 pro-democracy advocacy groups are partnering to organize the No Kings events.
What they're saying: "Donald Trump wants tanks in the street and a made-for-TV display of dominance for his birthday," the No Kings website said.
"A spectacle meant to look like strength. But real power isn't staged in Washington. It rises up everywhere else."
By the numbers: Millions of people are estimated to protest in more than 1,500 cities across all 50 states and commonwealths, organizers said.
Context: Trump proposed a military parade on his 79th birthday and the U.S. Army's 250th anniversary.
The Army predicts it will spend $25 to $45 million on the plan, an estimate that doesn't include Secret Service or law enforcement.
D.C. is not known for having military parades, but Trump has been vying for one since his first term."
